BACKGROUND: Fractures in the posterior aspect of the medial malleolus form an important subset of ankle fractures and the indications for fixation include involvement of > 25% of the articular surface or an articular step off by > 2mm. Several approaches have been described but there has been no recent study on the direct medial approach. METHODS: Five fresh frozen cadaveric ankles were dissected using the direct medial approach. A longitudinal incision of 10cm was centered directly over the medial malleolus and deepened straight down to the bone...

Articular cartilage injuries experienced at an early age can lead to the development of osteoarthritis later in life. In situ 3D printing is an exciting and innovative bio-fabrication technology that enables the surgeon to deliver tissue- engineering techniques at the time and location of need. We have created a hand- held 3D printing device (Biopen) that allows the simultaneous co-axial extrusion of bioscaffold and cultured cells directly into the cartilage defect in vivo in a single session surgery. This pilot study assesses the ability of the Biopen to repair a full thickness chondral defect and the early outcomes in cartilage regeneration, and compares these results to other treatments in a large animal model...

BACKGROUND: The purpose of this investigation is to determine whether osteoporotic intra-articular distal radius fractures surgically treated by filling all 7 distal screws of a volar plate will have a higher load to failure than those treated by filling only 4 distal screws. METHODS: Ten matched pairs of fresh frozen cadaveric forearms were randomized within each pair to be treated by using either all 7 of the distal holes of a volar plate or only 4 distal screws...

INTRODUCTION: Comminuted fracture of patella is most commonly treated by tension band wiring with cerclage wiring. Broken cerclage wiring after such surgery is not uncommon but intra-articular migration of broken cerclage wire is rarely known and described complication. CASE REPORT: A 51-year-old male patient of Indian origin which was treated, 15 months back for fracture patella with tension band wiring with cerclage wiring, presented with painful restriction of knee movements for the last 4 weeks...

The management of displaced, intra-articular calcaneal fracture represents a surgical challenge to even an experienced orthopedic surgeon. Plate osteosynthesis using an extended lateral approach is complicated by soft tissue problems, while those treated by closed reduction and percutaneous pinning cannot address all the intra-articular fragments sufficiently. The objective of our study is to evaluate restoration of subtalar joint and long-term functional outcomes in intra-articular displaced calcaneal fractures treated with transverse subcondral screws through a small incision on lateral aspect of calcaneus and percutaneously placed axial screws through the calcaneal tuberosity...

INTRODUCTION: Although the extended lateral approach is typically considered the gold standard of treatment for intra-articular calcaneal fractures, a limited lateral approach may be a good alternative in select cases. METHODS: Forty-seven consecutive patients with intra-articular calcaneal fractures treated using the sinus tarsi approach between March 2010 and April 2015 were retrospectively reviewed. The functional outcomes [including arc range of motion, Visual Analog Scale (VAS) score, and the American Orthopedic Foot and Ankle Society ankle/hindfoot (AOFAS) score], bony outcomes (bony restoration and bony union), and complications were evaluated...

BACKGROUND: This anatomic study investigated the distal humeral articular surface exposure achievable through a triceps-sparing oblique extra-articular osteotomy of the olecranon with a step-cut modification compared with the anconeus flap transolecranon apex distal chevron osteotomy. In addition, the bone contact surface areas of the osteotomized surfaces after transolecranon and extra-articular osteotomies were compared. METHODS: Seven pairs of fresh adult cadaveric elbow joints were examined...

PURPOSE: Joint fractures must be accurately reduced minimising soft tissue damages to avoid negative surgical outcomes. To this regard, we have developed the RAFS surgical system, which allows the percutaneous reduction of intra-articular fractures and provides intra-operative real-time 3D image guidance to the surgeon. Earlier experiments showed the effectiveness of the RAFS system on phantoms, but also key issues which precluded its use in a clinical application. This work proposes a redesign of the RAFS's navigation system overcoming the earlier version's issues, aiming to move the RAFS system into a surgical environment...

BACKGROUND: Tibial torsion is rotation of the proximal versus the distal articular axis in the transverse plane. This study used computed tomography (CT) to examine rotational malalignment in the crus following use of minimally invasive plate osteosynthesis (MIPO) technique in distal tibial fractures and evaluated effect of rotational difference on clinical outcomes and VAS scores. METHODS: Analysis of 24 patients who were operated on for closed distal tibial fracture with MIPO technique between 2010 and 2012 was conducted...

Volar dislocation of the proximal interphalangeal joint associated with dorsal fracture of the base of the middle phalanx is a rare injury, with only 38 cases published. We report here four such cases: three treated surgically and one conservatively. Patients had a mean age of 19.5 years. At an average follow-up of 3 years, pulp-to-palm contact was obtained and no pain was reported with regular daily activities. All patients considered themselves cured and were very satisfied with the result. Incomplete reduction of the dorsal fragment or the presence of localized articular impaction warrant surgical treatment...

Our study aimed to compare the anatomical result after treatment of intraarticular distal radius fracture with locking volar plates with and without arthroscopy. This was a retrospective, single-center study of intraarticular fractures. A volar locked plate was used for fracture fixation in all patients. Twenty patients were operated on with fluoroscopy only ("plate" group) and 20 operated using arthroscopy assistance ("arthroscopy" group). All patients underwent a CT scan before surgery and at 3 months postoperative...

The management of articular fractures is always a matter of concern. Each articular fracture is different from the other, whatever the classification system used and the surgical or non-surgical indications employed by the surgeon. The main goals remain anatomical reduction, stable fixation, loose body removal and minimal invasiveness.Open procedures are a compromise. Unfortunately, it is not always possible to meet every treatment goal perfectly, since associated lesions can pass unnoticed or delay treatment, and even in a 'best-case' scenario there can be complications in the long term...

In 1975, Blake and McBryde established the concept of 'floating knee' to describe ipsilateral fractures of the femur and tibia.(1) This combination is much more than a bone lesion; the mechanism is usually a high-energy trauma in a patient with multiple injuries and a myriad of other lesions.After initial evaluation patients should be categorised, and only stable patients should undergo immediate reduction and internal fixation with the rest receiving external fixation.Definitive internal fixation of both bones yields the best results in almost all series...

REVIEW
Jordi Tomás-Hernández
High-energy pilon fractures are challenging injuries. Multiple options are described for the definitive surgical management of these fractures, but there is no level I evidence for optimal management. The current management and recommendations for treatment will be reviewed in this article.Anatomical reduction of the fracture, restoration of joint congruence and reconstruction of the posterior column with a correct limb axis minimising the soft-tissue insult are the key points to a good outcome when treating pilon fractures...

Humeral hemiarthroplasty, anatomic total shoulder arthroplasty, and reverse total shoulder arthroplasty all rely on a prosthetic articular surface fixed to the proximal humerus. Humeral implant designs have changed considerably as a result of improved understanding of proximal humeral anatomy and prosthetic biomechanics. Fixed, monoblock implants have been superseded by modular implants with variable inclination, offset, version, and stem length. Press-fit designs now commonly have surface coatings that allow bony ingrowth...

Superior patellar dislocation is a very rare pathology, which happens in middle age. We report a case of spontaneous superior patellar dislocation, which occurred at 30 years of age. Differential diagnosis is patellar tendon rupture, which could be reliably excluded by clinical examination and radiographs. Reduction manoeuvres should be tried with diluted intra-articular local anaesthetic for hydrodilatation to gain mechanical advantage. Splinting the knee in gentle flexion is recommended if general anaesthetic is employed...

BACKGROUND: Mallet finger is a common injury of the extensor tendon insertion causing an extension lag of the distal interphalangeal joint. METHODS: We reviewed the most current literature on the epidemiology, diagnosis, and management of mallet finger injuries focusing on the indications and outcomes of surgical intervention. RESULTS: Nonoperative management has been advocated for almost all mallet finger injuries; however, complex injuries are usually treated surgically...

The Bosworth fracture is a pattern of fracture-dislocation of the ankle joint with fixed dislocation of the proximal part of the fibula behind the posterior malleolus. It is a rare injury, which requires high index of suspicion for diagnosis. Fixed dislocation of the fibula does not allow for closed reduction, so open reduction and fixation of fibula or tibia is required. We present a case report of a patient who suffered a Bosworth fracture, with associated medial malleolus fracture. She underwent surgical treatment with open reduction and internal fixation of the fibula and tibia...
